mai using password_hash is the recommended way to store passwords. don't separate them to db and files. let's say we have the following input: $password = $_post['password'];. i don't validate the input just for the sake of understanding the concept. you first hash the password by doing this: php password_hash() is a predefined (built in) function on php . and above. verifiable with password_verify() but non reversable. easy way to change hashed php password.

php . now comes baked with a password_hash function to generate secure, oneway hashes along with a password_verify function to match a hash with the given password—if you're a php developer, you should always be securely storing user passwords, no excuses. developers have a huge  php | crypt(), password_hash() functions. in the previous article on md(), sha(), and hash() functions we saw that one of the major drawbacks of the method was that these algorithms were very fast due to less complexity and thus more vulnerable to attacks, they are even suggested not to use in a fullfledged project of

according to the documentation for password_hash() , the default cost is . on my machine this takes about ms to compute. while better than a nonadaptive hash function (think plain sha or md), i'd prefer that be closer to ms (cost on my machine). the general recommendation i make is
